// #6315 / #6345 — a single generic upstream 403 on a no-credential ("authType:
// none") provider was permanently banning the whole
// connection (classified as FORBIDDEN, a terminal type). These providers are
// free/stateless — there is no real account/credential to revoke, so a bare
// 403 should be RECOVERABLE (null) and handled by the existing connection
// cooldown/retry layer, same as apikey providers already are.
